Theme: 26 on 03/02

Author/Opus: This is the 152nd puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: This puzzle combines Yajisan-Kazusan with Tapa with additional rules.

Left grid = Yajisan-Kazusan (No 2×2): Shade some cells black so that all unshaded number and arrow clues indicate the exact count of shaded cells in the given direction (all counts extend through gaps in the grid). Shaded cells cannot share an edge, and all white cells must remain connected as part of a single contiguous group. It is allowed to shade over some of the numbered cells; a shaded over clue may or may not be true. Also, no 2×2 area inside the grid can be fully white.

Right grid = Tapa: Shade some empty cells black to create a single connected wall. Numbers in a cell indicate the length of consecutive shaded blocks in the neighboring cells. If there is more than one number in a cell, then there must be at least one white (unshaded) cell between the black cell groups. Cells with numbers cannot be shaded, and the shaded cells cannot form a 2×2 square anywhere in the grid.

Additional rule 1: Clues in the middle of the grids indicate the sum or the difference of the number of shaded cells in that row between the grids (possibly both).

Additional rule 2: The shading of the green outlined regions is equivalent in the two grids in the shared cells (if the cell labeled “A” in the illustration below is shaded in one grid it must be shaded in both grids). Note that the 3 and 2 share all locations except for the bottom vertical stem of the numbers which is shifted.

Answer String: For each marked row, enter the length in cells of each of the unshaded segments from left to right in the Yajisan-Kazusan followed by the length of each of the shaded segments from left to right in the Tapa. Separate each row’s entry from the next with a comma (but do not use commas in between the Yajisan-Kazusan and Tapa entry parts in a given row). Enter both digits for any two-digit large segment in an entry.

### Update 1: Hidden Puzzle in the Snake Pit

See this PDF for the full week of Snake Pit puzzles from Carl Worth.

If you noticed anything unusual about the puzzles this week, it probably wasn’t an accident. Carl has hidden an additional puzzle within the six Snake Pits. Find and solve that puzzle to determine some counsel he’d like to share with you, perhaps something to use when approaching puzzles like these.

The final answer to the hidden puzzle consists of eight characters (specifically four CAPITAL letters followed by four numbers). Nothing outside of the six Snake Pits has any bearing on the hidden puzzle, including this text.

Theme: Up to Eleven (for patron Phleb)

Author/Opus: This is the 111th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place the words into the grid (one letter per cell) so that they do not touch each other, not even diagonally, and so that they can be read in a straight line in a vertical or horizontal direction. Some letters in the words are already given in the grid. Then find a path that passes through every cell of the grid, starting with the first letter of the first word, passing through the words in order from their first letters to their last letters, and ending at the last letter of the last word. Ignore the black cell.

Or see this example:

Answer String: Enter the number of turns the path takes between each of the words in order as a single string of numbers. (Ignore turns in cells with letters.) The answer for this example is “224”.
